Priority for customers

There is great improvement these days and I wish it stays as is and let's get more. Few mistakes are taking place but it's normal.... But please check on.... - when a customer is at the cashiers they should be assisted and get done with then they can gossip after amongst themselves - the workers should not be given priority to pay for their food or groceries in front of customers without customer's request. Some will also be in a hurry but they just do without communicating. Suggestion: can workers have their till for such not to inconvenience customers.
